To all whom t may concern:

Beit known that l, FRANK A. MOORE, a citizen of the United States ofAmerica, residing at Garee, in the county of Clearfield and State ofPennsylvania, have invented certain new and useful Improvements inHose-Couplers,

of which the following is a specification, ref-y y A further object ofthe present invention is to provide means for automatically locking thesections after they have been coupled together, which means is readilyaccessible'to permit the unlocking of the sections or members whendesired.

Briefly described, the invention comprises a male and female member orsection, the one provided with a recess to receive the eXtension carriedby the other section or member. One of the sections or members isprovided with openings cut therethrough near its` engaging end and alsohas oppositely-disposed recesses or grooves leading into these openings,which recesses or grooves receive oppositely-disposed lugs on the othermember or section adapted to enter the recesses or cutaway portions ofthe engagingsection and interlock. These lugs are provided with teethwhereby to lbe engaged by the spring member carried by the oppositesection for holding the two sections or members in the locked position,all of which construction will be hereinafter more fully described.

In describing the invention in detail reference is had totheaccompanying` drawings, forming a part of this specicatiomand whereinlike numerals of reference indicate like parts throughout the severalviews,in which- Figure 1 is a top plan view of my4 improvedhose-coupling, showing the members or sections in the coupled position.with the y hose secured thereon and shown in horizontal section. Fig. 2is a detail end view of the male member or section. Fig. 3 is a likeview of the female member or section. Fig. 4 is a transverse verticalsectional view of the sec- Amodified form of locking means.

tions or members after coupled together,taken on the lineV l l of Fig.Vl. Fig. 5 is a top plan view of the sections or members coupledtogether and partly broken away, showing the Fig. 6 is a longitudinalsectionalview of the members or sections coupled together and partlybroken away.

To put my invention into practice, I provide a male member or section l,provided with a tubular extension 2, having oppositelydisposedinterlocking lugs 3, which lugs may be provided on their outer face withteeth 4, as seen in Figs. l, 2, 4, and 6, or with teeth 5 on their outeredge, as seen in Fig. 5. The female member 6 is provided with an annularrecess 7 to receive the extension 2, a gasket S being placedagainst theinner wall of said recess to receive the inner'end of said eXtension 2.This female member is constructed with annular peripheral flanges 9 10,and made through the said member 6 between these two flanges on oppositesides of the member are openings 11. The lugs 3 are adapted to lenterinto these openings and turn against the inner edge of the flange 10through the medium v of grooves or recesses l2 made inthe innercircumference of the female member at the outer end thereof. A springmember 14 is permanently attached to the female member 6, as seen inFig. 4f, whereby to engage with teeth 4 on the outer face of the lugs 3,or this spring member may be attached to the fiange 9T as seen in'Fig.3, whereby to engage with the teeth 5 on the outer edge of the lugs. Itwill thus be seen that these lugs may be constructed with the teeth onthe outer face or on the outer edge, as may be desired, a springpreferablyprovide each of the members'with recesses l5, as shown in'Fig.1, whereby to receive the ordinary spanner-wrench, if found desirable touse same. n

To couple the members,the oppositely-disposed lugs 3 are inserted in thegrooves or recesses l2 and one of the members is given a quarter-turn,or both the members may be rotated in opposite directions, whereby toturn the lugs 3 into the openings ll and lock the inner edge of. theselugs against the inner edge of the annular iiange 10 of the femalemember. By providing the teeth on each of the TOO lugs 3 it Will beobserved that it is immaterial as to how the members are connected-thatis, it Will not require the insertion of a particular lu g 3 into aparticular recess l2, as the spring member will engage With either oneof the lugs. The coupling constructed in accordance with this principleis easily and quickly made, and when the members or sections are joinedtogether the couplingis rigid and eiective.

YVhile I have shown and described my invention in detail as it ispracticed by me, yet it Will be noted that various slight changes may bemade in the details of construction Without departing from the generalspirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a hose-coupling, a male member provided with a reduced tubularextension, lugs having their outer faces toothed carried thereby, afemale member provided with annular peripheral flanges, and havingopenings formed therein between the said flanges on opposite sides ofthe said member, the female member being further provided withoppositely-dis posed longitudinal grooves formed in its innercircumference communicating With the firstnamed openings, the lugs ofthe male me1nber being` adapted to be guided by the grooves into saidopeningsrand turned into engagement with the inner edge of one of saidanges, and means for locking the lugs in engagement with said flange tolock the coupling, substantially as described.

In testimony whereof I affix my signature in the presence of twoWitnesses.
